Research on Identification and Calibration Method of Battery Nickel Sheet for Vision Guided Robot
Aiming at the difficulty of automating the placement of nickel sheets in battery PACK line,the identifica-tion and disordered grabbing of nickel sheets in a battery automatic production line were taken as an example,and theoretical analysis and test were conducted.The affine transformation matrix between the robot and the visual cam-era is established by using the Eye-to-Hand three-point hand-eye calibration method.The feature extraction and shape-based template matching algorithm were used to identify the battery nickel slice images by Halcon software platform,and the influence of various positions and poses on the recognition speed and accuracy was studied.Final-ly,a test platform was built for verification.The research results show that the recognition speed of this method reaches 32.3 ms,and the recognition accuracy reaches 0.9521.It can identify more than 10 nickel pieces with differ-ent poses and shapes at one time,and can accurately and effectively guide the robot to operate the materials,which meets the needs of the automatic production line and has good reference value for similar types of operations.
